SCA: security update for better-auth (GHSA-hjpm-7mrm-26w8)

medium Tenable Cloud Security Plugin ID 420995

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Better Auth is an authentication and authorization library for TypeScript. Prior to version 1.1.21, the
 application is vulnerable to an open redirect due to improper validation of the callbackURL parameter in
 the email verification endpoint and any other endpoint that accepts callback url. While the server blocks
 fully qualified URLs, it incorrectly allows scheme-less URLs. This results in the browser interpreting the
 URL as a fully qualified URL, leading to unintended redirection. An attacker can exploit this flaw by
 crafting a malicious verification link and tricking users into clicking it. Upon successful email
 verification, the user will be automatically redirected to the attacker's website, which can be used for
 phishing, malware distribution, or stealing sensitive authentication tokens. This CVE is a bypass of the
 fix for GHSA-8jhw-6pjj-8723/CVE-2024-56734. Version 1.1.21 contains an updated patch. (CVE-2025-27143)
